Chromatic aberration.

Глоссарий терминов в фотографии
    Longitudinal (axial)


Loca, английский
  1. Chromatic aberration.

  2. Longitudinal (axial) chromatic aberration.

  3. Marine-board. see marine boards.

  4. Loss-of-coolant accident




Chromatic, английский
  1. Having to do with color, or wavelength.

  2. Relating to or produced by color.


Chromatic aberration, английский
  1. Optical term, which refers to the distortion of an image as a result of a scattered focal point caused by a defect in a lens. a combination of lens can be used to correct this effect.

  2. Chromatic aberration. failure of a lens to focus all colours at the same point. the aberrations can be along the optical axis (longitudinal ca, or loca) or off-axis (lateral or transverse ca, tca).

  3. An optical defect of a lens which causes different colors or wave lengths of light to be focused at different distances from the lens. it is seen as color fringes or halos along edges and around every point in the image.

  4. Also known as the purple fringe effect. it is common in two megapixel and higher resolution digital cameras (especially those with long telephoto zoom lenses) when a dark area is surrounded by a highlight. along the edge between dark and light you will see a line or two of purple or violet colored pixels that shouldn`t be there.

  5. Also known as color fringing, chromatic aberration occurs when the collective color wavelengths of an image fail to focus on a common plane. the results of chromatic aberration are most noticeable around the edges of high-contrast images, especially toward the edges of the frame. chromatic aberration is most common on less expensive lenses, although even the best optics can occasionally display lower levels of chromatic aberration, under certain conditions.

  6. In terms of lens optics it is the failure of the lens to focus all colours (rgb) at the same point. it shows up as colour fringes in areas of the image where dark meet light (think edge of a building against the sky). it is more common in wide angle lenses, and those of inferior optics (kit lenses). it is correctable, to some degree, using photoshop, lightroom or software of your choice.

  7. Also known as purple fringing. it is fairly common in 2mp digital cameras and above, especially if they have long telephoto lenses. you can see it when a dark area is surrounded by a highlight. in between the dark and light, you may see a band of purple pixels that shouldn’t be there. there are ways of removing this which i have covered in the photoshop section.

  8. When a lens causes white light to be broken into various component colors with each focus at a different distance from the lens, commonly producing color fringe around a viewed image.


Chromatic aberration or, английский
    Transverse (lateral)


Chromatic aberrations, английский
    Image distortions caused by wavelength-dependent optical effects


Chromatic adaptation, английский
    The eye`s ability to compensate, after a few minutes, for variations - sometimes drastic ones - in the color of light sources so that everything appears normal. tip: since the film doesn`t compensate, you may want to use a color-temperature meter.


Chromatic color, английский

Chromatic dispersion, английский
  1. Расширение светового импульса, вызванное разницей скоростей распространения волн различной длины, составляющих данный импульс (см. также коэффициент преломления)

  2. The frequency dependence of the phase velocity in a transparent medium

  3. Wavelength-dependent pulse spreading in optical fibers, measured in pico seconds (of pulse spreading) per nanometer (of source bandwidth) per kilometer (of fiber length). it is the sum of waveguide and material dispersion. reduced fiber bandwidth caused by different wavelengths of light traveling at different speeds down the optical fiber. chromatic dispersion occurs because the speed at which an optical pulse travels depends on its wavelength, a property inherent to all optical fiber. may be caused by material dispersion, waveguide dispersion, and profile dispersion.

  4. Хроматическая дисперсия


Chromatic dispersion (cd), английский
    The variation in the velocity of light (group velocity) as a function of wavelength. it causes pulses of a modulated laser source to broaden when traveling within the fiber, up to a point where pulses overlap and bit error rate increases


Chromatic dispersion coefficient, английский

Chromatic gray, английский
    Grays that exhibit a subtle, but discernible hue.


Chromatic simultaneous contrast, английский
    Simultaneous contrast concerning color changes that occur due to the influence of the surrounding colors


Chromatic аberration, английский

Chromaticity, английский
  1. The color quality of light which is defined by the wavelength (hue) and saturation. chromaticity defines all the qualities of color except its brightness.

  2. The color quality of light definable by its dominant (or complementary) wavelength and its purity, taken together. chrome green 1. a green pigment made by blending lead chromate yellow and iron blue pigments. 2. chromium oxide.

  3. Цветность; хроматичность

  4. The quality of color expressed as a function of wavelength and purity.


Chromaticity diagram, английский

Chromaticity, chromaticity coordinates, английский
    Dimensions of a color stimulus expressed in terms of hue and saturation, or redness-greenness and yellowness-blueness, excluding the luminous intensity. generally expressed as a point in a plane of constant luminance. see cie xy chromaticity diagram.


Chromatics, английский

Longitudinal, английский
  1. Generally parallel to the direction of the wood fibres.

  2. Продольный

  3. Generally, parallel to the direction of the wood fibers.

  4. Продольный, относящийся к долготе, стрингер

  5. [1] extending in the lengthwise direction, as distinguished from transverse. [2] said of any fore-and-aft structural member, such as a frame or bulkhead.

  6. Running lengthwise.

  7. Along the length of a structure.

  8. Direction parallel to the long axis of an object and perpendicular to its radius — for example, down the length of a cylinder. compare circumferential; radial; transverse. lot tolerance percent defective (ltpd): the poorest quality, in percent defective, individual lot that is acceptable in a sampling plan. ltpd is the percent defective that will be accepted by the sampling plan at most 10 percent of the time. with such a plan, the producer agrees to supply just enough nonconforming product such the consumer will accept the lot using the agreed to sampling plan and acceptable quality level. compare acceptable quality level. lumen (lm): si photometric unit of luminous flux, weighted according to the photopic vision response. one lumen equals the light emitted by one candela (cd) point source into one steradian (sr) solid angle (1 lm = 1 cd/sr).


Lightroom, английский
    Lightroom, a popular software application for processing images from digital cameras. developed by adobe.
